Vintage enamel black and white flower pin and earrings

Pretty black and white enamel over metal large daisy flower pin with matching clip earrings. Center is realistic crushed glass under enamel, and shows a nice texture contrast against the smooth petals. Large pin measures just over 3" diameter. Earrings are 1 3/8" diameter. All three pieces are excellent with no rust, or chipping. A very striking set. No makers mark.
